Principles of Operation

Exterior Mirrors

The movement of the LH and RH exterior mirror glass is controlled by the exterior mirror control switch and the LH and RH exterior mirror motors. Adjusting the exterior mirror switch to the LH or RH position determines which exterior mirror motor is controlled. The exterior mirror control switch logic is the selected movement request from the exterior mirror control switch. When the exterior mirror control switch is adjusted to the left, right, up or down position, the exterior mirror control switch supplies voltage and ground to the selected exterior mirror motor to move the exterior mirror glass to the desired position.

The exterior mirrors use a jumper harness between the vehicle wire harness connector and the exterior mirror motor. The exterior mirror jumper harness is integral to the exterior mirror. If a concern with the exterior mirror jumper harness exists and cannot be repaired, a new exterior mirror must be installed.

Heated Exterior Rear View Mirror

The rear window defrost/heated mirror switch controls the operation of the heated exterior rear view mirrors. The heated exterior rear view mirror power is supplied by the rear window defrost/heated mirror relay through the Central Junction Box (CJB) fuse 167 (7.5A), which isolates the heated exterior mirrors from the rear window defroster system in the event of a concern.

Interior Rear View Mirror With Video Display

Vehicles equipped with a rear video camera system displays a video image on a portion of the interior rear view mirror glass when the gear selector is in REVERSE. For information on the rear video camera system, refer to Parking Aid Description and Operation.
